..fyi


WASHINGTON - States no longer will have to add corn-based ethanol or MTBE to gasoline to fight pollution — a requirement that costs as much as 8 cents a gallon — under rules announced Wednesday by the Environmental Protection Agency.

Was it ever in marine gas?

Re: Marine Lubrication
 

Noticed Amsoil has 2 different Marine Gaer oil's, which one?

Re: Marine Lubrication
 

[QUOTE=Hydrocruiser]

Well I decided that if a company deserves your business they should make a product specific to marine use.

Does this mean that you wont run v-twin (motorcyle oil) in a hi-perf marine engine?

Kind of contradicts what the whole thread has been about :D

Limiting our choices to marine approved products would dramatically shorten this topic :evilb:

Re: Marine Lubrication
 

An out-drive IMO is just a gearbox. If it is properly sealed then any good gear oil, or great gear oil like the HD Shockproof will work very well. If your drive is leaking the best "marine" oil in the world isn't going to avoid problems down the road.

A pressure and vacuum test annually + good gear oil is the best bet

Re: Marine Lubrication
 

Well I heard pressure and vaccuum testing can actually stress seals...only do it if you think you have a leak they tell me..

Amsoil Gear Lube in it's new formulation was out most of last season and it performed very well. Teagues gave it very high ratings when used in thier Platinum drives. It is a great product and the one I would personally go with. It's made for offshore applications and it will extend your drive's life.

-Excellent Gear and Bearing Protection even
when contaminated with 10% water
-Reduced Friction and Wear
-Rust and Corrosion Protection
-Long Seal Life ...additives for drive seal materials!
-Superior Foam Prevention

This plus a drive shower and you are good to go....Fred will give you a shower just ask him.. :D

Re: Marine Lubrication
 

[QUOTE=Wobble]I see your point and it is well taken. It happens that motorcycle oils are the toughest beasts out there.

As far as out-drive lubes go there is more specific chemistry needed I feel for an outdrive vs. an axle. That plus testing. Auto lubes are not tested with water contamination or foaming as drives are much more punishing and subject to different environments and temperatures. The seals are also different.

The Mobil1 V-twin has lots of anti-corrosion agents and a load of ZDDP. It should be labeled "marine" as well as it is perfect for the application.

Re: Marine Lubrication
 

I was asked why additives such and Zinc..Phosphorous..Calcium..Antimony..Molybdenum etc are so important...

Well these agents are known as "Boundary Lubricants"...they say a picture is worth a thousand words...any questions?? :D

Re: Marine Lubrication
 

How does Synergyn gear oil stack up? I did a search on this thread, but it only came up once. :chimp:

Re: Marine Lubrication
 

No idea..

Re: Marine Lubrication
 

Where's a good place to order the Mobil1 V-twin from?

Re: Marine Lubrication
 

Hydro, calcium is not a reserve boundry lubricant, however it os still very important, it is in the detergent package, without it the contaminents of combustion would not be removed when you drain the oil.

Re: Marine Lubrication
 

Any good automotive gear oil rated GL-5 would work extremely well in an outdrive application. Synthetics would be better than petroleums. As far as working with water contaminination....... don't. You should change your gear oil at the first signs of water contamination, regardless of how much water your gear oil can "hold". Water is a lousy lubricant. Ken

Re: Marine Lubrication
 

I felt the same way and you probably are right...but Amsoil told me they use calcium as an anti-wear agent...think they are right?

Re: Marine Lubrication
 

I have seen it at WalMart for $7/qt

Re: Marine Lubrication
 

NO, I do not think they are right. I have spoken to many Amsoil "reps" and they all say the product is the greatest but they do not have any knowledge of the chemistry. They do however have a bunch of graphs and charts"all from their own labs"showing the superior performance of their lubes. They still do not own a refinery or an additive company but say the "first in synthetics". I think that honor went to the Germans in WWII. The Germans had no oil fields available to them. I also question the distribution of the product, even thought my barber can become a Amsoil dist. I don't think I would trust his knowledge on oils. Ken

Re: Marine Lubrication
 

Wow you beat me to the punch to post it. I forgot I had this information 5 months ago. Just never thought to post it.

Re: Marine Lubrication
 

I can hook you up with an ExxonMobil distributor in your area.. I've hooked up 30 ppl so far on here and counting.. I just have to get into my XOM distributor directory. E-mail me and I can send you a copy of the list of XOM distributors in your area. They've been very helpful all over the country.

Re: Marine Lubrication
 

I cant find the M-1 5w-40 yet, will be putting it in my 06 Duramax at the next change which will be around 12k miles.

Re: Marine Lubrication
 

It's no longer the 5w40 tuck and SUV. It's now 5w30 and 5w40 Turbo Disel b.c of a lawsuit. It's was the same as the Delvac 1. You should see the 5w30 truck and SUV soon.

Re: Marine Lubrication
 

I am refering to this one

Mobil 1 Truck & SUV 5W-40
Fully synthetic Mobil 1® Truck & SUV Formula is engineered for hard-working gasoline and diesel engines. It offers outstanding wear protection, oil consumption control and performance reserve. Whether hauling or towing heavy loads, driving off-road or just dealing with stop-and-go driving, Mobil 1 Truck & SUV provides outstanding protection for gasoline and diesel engines.

http://www.mobiloil.com/USA-English/...SUV_5W-40.aspx

Are you saying that it's actually 5-30 Delvac?

Re: Marine Lubrication
 

It's been discontinued due to a lawsuit. It is Delvac 1 in a Mobil 1 bottle. That was part of the lawsuit, for missrepresentation or something?!?

Anyway, they are coming out with a 5w30 Truck and SUV and a Turbo Diesel 5w40 that should be on the shelves by now. They were released Feb 15th, 2006. If you want I can get you int ouch with a Mobil distributor in your area. They may have it before Walmart. ExxonMobil is doing a great job at confusing us all!!!! Tust me, we are opening and canceling products everyday. It's hard these days to be a distributor for them, but they are the best around..

Re: Marine Lubrication
 

The communication is on the post on the other page...

Re: Marine Lubrication
 

What ever they call it Mobil 5W-40 is great for towing vehicles to a ZO-6...absolutely great stuff. Period.

But no...not for offshores...you know what goes under the cap in those birds. :D

Re: Marine Lubrication
 

I will wait for the M-1 turbo oil. Thanks for your offer re distributors, i am aware of a couple here if needs be.

Re: Marine Lubrication
 

How much ZDDP do I need?

Most all oils have about 1%.

1300 ppm is not equating to 1% ZDDP.

Most GOOD oils, the ones that are loaded, like racing oils, Mobil 1's, etc, say 1-4.9%, BY WEIGHT.

Remember ZDDP, has two alkyl branches, and phoporous, besides zinc.

I'm past that, and need a missing factor to do the math, to make this make sense.

Re: Marine Lubrication
 

So I was asked for my personal choices of lube/filtration products for 2006's season...

My reply:

Gearlube:
#1 Amsoil Marine
#2 Mobil-1 75W-90
#3 Mercury HP

Oil Filters:
#1 Wix Racing
(Fram racing for racing engines that need more flow)
#2 K&N
#3 Mobil-1 or Amsoil SD

Synthetic Oil
#1 Mobil-1 V-Twin
#2 Mobil-1 15W-50
#3 Amsoil Marine 15W-40

Conventional Oil:
#1 Kendall or Castrol GT 20W-50
#2 A 15W-40 Diesel such as Delvac or Rotella
#3 Straight weight 40 Kendall or Mercury 20W-40

Just my favorites....everybody has their own I am sure. :drink:

Re: Marine Lubrication
 

Got a good question..

Does the Mobil 1 Extended Performance meet GF-4 specifications? How did the new specification impact the development of the high-endurance product line?

"Mobil 1 Extended Performance contains an extra performance additive to help deliver exceptional performance and protection. This fully synthetic technology is designed specifically for longer service intervals. Appropriate viscosities of Mobil 1 Extended Performance also meet all the requirements for GF-4. Additionally, they exceed the requirements of API SL/CF and various ACEA (European) specifications".

Mobil got it right now! :D

Re: Marine Lubrication
 

I saw on page 3 or 4 someone didn't know why auto racers used such heavy weight oils. The reason they use heavy weight oils is to reduce windage. A 10W-30 oil that is lighter gets sucked up towards the crank at high RPMs and slows down the rpm. I believe Car Craft or some other hot rod magazine did dyno test back in 92-94 issue.

Good thread here!
Steve

Re: Marine Lubrication
 

I would of thought that is why they use windage trays. A heavier viscosity oil will also offer more film strength which in turn produces less engine wear. On the negitive side a heavier oil will produce more drag hence less horsepower. Is the horsepower loss measurable, probally. Would you notice the loss driving your boat, I doubt it. Ken

Re: Marine Lubrication
 

Been told i should change oil brands from merc to mobil1 since i installed whipples on my 525's.Turning a few more rpms and adding boost.Should I and what do you reccomend ?

Re: Marine Lubrication
 

Any good motorcycle specfic lubricant. Not a rebranded passenger car motor oil (PCMO). I would suggest Spectro Golden 4 20w50. Ken

Re: Marine Lubrication
 

OK folks, I've been reviewing everything I can about this subject and want to put some of it to use. Here's my situation.

Last year I was running 502 blower motors. Stock GM 6-qt oil pan, stock oil pumps, large oil coolers, -10An lines all the way through (No 90degree turns), Permacool oil t'stats, water crossovers with no t-stat (water temps never even registered high enough to show on my gauge), M1 15w50 oil, and Napa Gold (Wix) filters. Oil pressure was always in the 55# range at cruise, and oil temps (on filter pad before cooler) would be in the 215-230 range. At WOT they'd spike to 250-260.

This year I've built up the engines to 540ci, and removed the blowers. High volume oil pumps (Moroso 22160), Stainless Marine t-stat kit (140# t-stat) for cooling, straight 30wt oil for break-in using Napa "black" filters. Nothing else has changed. I water tested yesterday and here's the results:

Port engine - water temperature peaked at 160, oil temp would hit 230 at 3000rpm, and then climb higher as RPMs increased. Oil pressure at 55-60# at cruise and above.

Star engine - water temperature peaked at 140, oil temp would hit 215 at 3000rpm, and then climb higher as RPMs increased. Oil pressure at 55-60# at cruise and above.

In both cases I never let the oil temp exceed 260# - I'd back off the throttles and the temp would drop accordingly. I can't running over about 3300rpm for extended periods of time (a few miles) without tempertaures getting too high. So here's my plan of attack. Tell me if it sounds reasonble.

1) Differences in water temps may be caused by some type of blockage, so I'm going to backflush the cooling system. If I can get water temps to be the same for both engines, then I'm going to assume that oil temps will be closer to the same.

2) I need to "dial in" the carbs and timing to make sure I'm not running lean and/or wrong timing. I was running 10 degrees BTDC and changed one engine to 8, but that didn't seem to have an impact. (Any suggestions on where it should be?)

3) Increase in oil temps may be caused by running a t-stat this year in my cooling system (increased engine temp = increased oil temp). Possibly combined with the high volume pump trying to pump oil through a standard volume filter.

So I'm going to convert over to the HP6A filters and go back to my M1 15w50 synth oil now that the engines are broke in (@ 2 hours). Any other suggestions at this point?

Re: Marine Lubrication
 

anybody know the part number for the wix oil filter for the 525efi ?

Re: Marine Lubrication
 

My oil gauge temp would go to 300+ after WOT. So I bought a big oil cooler from Teague and there was no difference. So I went and bought a infrared temp gun and took temp from oil pan and filter and even the oil lines and the gun never read anything higher then 240 even when gauge read 300. So my gauge was miss leading me the hole time. Plus I did the hand check. If oil was actually 300 degress, would I be able to hold my hand on the oil filter?

Re: Marine Lubrication
 

230 degrees is not hot for engine oil. The oil is tested in the lab at 210 for viscosity. 300 degrees now that is getting hot. Ken

Re: Marine Lubrication
 

Sounds like a mismatched sender. Make sure you get one made by the same people as your gauge and then verify it by dunking it in boiling water, should read about 212. I ran into the same problem. New sender from Gaffrig solved the problem.

Re: Marine Lubrication
 

I have been running M-1 v-twin 20/50 for the past year, better oil pressure at hot idle and wot, not whipple charged but I run hard.

Re: Marine Lubrication
 

After reviewing these posts, I'd like to run Mobil 1 15w/50, but I'm I've heard about some people 'springing' oil leaks, in high hour engines. My 1999 502efi mercruiser has 220 hrs. Is it safe to start using a synthetic?? Thanks...

Re: Marine Lubrication
 

You mention Amsoil Marine 15W-40 as #3. Why not Amsoil MCV or ARO 20W-50 ? I would think that the higher viscosity should protect the engine better in case it is run hard. Any specific properties of the Amsoil Marine 15W-40 that makes it superior compared to their MCV or ARO 20W-50 oils ?
